parentUpdate the file format specification draft. The new one is (diff)
downloadxz-7d17818cec8597f847b0a2537fde991bbc3d9e96.tar.xz
Update the code to mostly match the new simpler file format
specification. Simplify things by removing most of the support for known uncompressed size in most places. There are some miscellaneous changes here and there too. The API of liblzma has got many changes and still some more will be done soon. While most of the code has been updated, some things are not fixed (the command line tool will choke with invalid filter chain, if nothing else). Subblock filter is somewhat broken for now. It will be updated once the encoded format of the Subblock filter has been decided.
